In general,
bearing support stations on screw conveyors must be classified as severe
service. The materials handled are often corrosive and abrasive and sometimes
moisture laden. Conditions are encountered that can disintegrate conventional
bearings in extremely short time while also scoring and pitting the journals.
In contrast, POBCO hanger bearings are unaffected by most
corrosive materials and work well even under moist conditions. When abrasive
materials are being handled, the small amount of particles that reach the
bearing surface become embedded in the POBCO material without
adversely affecting the bearings' performance. These factors allow
POBCO to handle a wide variety of materials on this equipment.
POBCO hanger bearings are self-lubricating for life. They
are ideal for installation in screw conveyor assemblies, where the bearings are
usually inaccessible. The long life of POBCO bearings and the
elimination of excessive shaft wear are major factors in reducing high
maintenance costs and periodic shutdowns.
POBCO bearings
are the quietest bearings made for screw conveyors, whether operating slowly or
at an accelerated pace. They eliminate the noisy metal-to-metal sounds inherent
is such machinery employing metal bearings. The hanger bearings listed are the
most commonly used. Non-cataloged hanger bearing sizes and shapes, including
sizes larger then those listed, are available. |
